Question

    Since the first Earth Day in 1970,Americans have gotten a lot “greener” toward the environment(环境).“We didn’t know at that time that there even was an environment,let alone that there was a problem with it,”says Bruce Anderson,president of Earth Day the USA.

But what began as nothing important in public affairs has grown into a social movement.Business people,political leaders,university professors,and especially millions of grass-roots Americans are taking part in the movement.“The understanding has increased many,many times,”says Gaylord Nelson,the former governor from Wisconsin,who thought up the first Earth Day.

According to US government reports,emissions (排放)from cars and trucks have dropped from 10.3 million tons a year to 5.5 million tons.The number of cities producing CO beyond the standard has been reduced from 40 to 9.Although serious problems still remain and need to be dealt with,the world is a safer and healthier place.A kind of “green thinking” has become part of practices.

Great improvement has been achieved.In 1988 there were only 600 recycling(回收利用)programs;today in 1995 there are about 6,600.Advanced lights,motors,and building designs have helped save a lot of energy and therefore prevented pollution.

Twenty-five years ago,there were hardly any education programs for environment.Today,it’s hard to find a public school,university,or law school that does not have such a kind of program.“Until we do that,nothing else will change!” says Bruce Anderson.

1.According to Anderson,before 1970,Americans had little idea about______.

A.the social movement

B.recycling techniques

C.environmental problems

D.the importance of Earth Day

2.Where does the support for environmental protection mainly come from?

D.University professors.

3.What have Americans achieved in environmental protection?

A.They have cut car emissions to the lowest.

B.They have settled their environmental problems.

C.They have lowered their CO levels in forty cities.

D.They have reduced pollution through effective measures.

【解析】

这是一篇夹叙夹议的文章，通过叙述和议论表达美国人通过有效措施减少污染的行为和效果。

1.

细节理解题。通过审题可定位于before 1970：We didn’t know at that time that there even was an environment, let alone that there was a problem with it,我们那时候不知道甚至有环境这一说法，更不用说与之相关的问题了。可以推知美国人在1970年以前对环境保护问题知之甚少。C选项切合文意。故选C。

2.

细节理解题。通过审题得知关键词信息是the support…mainly come from。故定位于：Business people, political leaders, university professors, and especially millions of grass-roots Americans are taking part in the movement.商务人士，政治领导人，大学教授，尤其是数以百万计的普通美国人都参与到这项运动中来。可以推知支持者主要来自于普通民众。故A选项the grass-roots level切合文意。故选A。

3.

逻辑推理题。此题要综合各段信息。根据第三段的信息得知：小轿车和卡车排放量从一千零三十万吨减少到五百五十万吨。产生超标CO的城市数目从40减少到9个。尽管……但一种“绿色思想”已经变成行动的一部分了。第四段开头：Great improvement has been achieved.已经取得了伟大的成就。接下来讲述的是先进的灯光，摩托和建筑设计帮助节约大量能源从而阻止污染这一事实。第五段讲述的是25年前环保教育很难发现，但现如今几乎所有各级各类学校都开设有这样的项目。因此可归纳出美国人采取多种有效措施来减少环境污染。而D选项：They have reduced pollution through effective measures.题目已经通过有效措施减少污染切合文意。故选D。
